Reproduction and population growth in free-ranging mantled howling monkeys.
Abstract
Free-ranging mantled howling monkey (Alouatta palliata Gray) females experienced a
regular estrus cycle averaging 16.3 days, demonstrated sexual skin changes, and participated
in multiple matings before becoming pregnant. Gestation averaged 186 days. The average
interval between births was 22.5 months. Sexual maturity occurred at approximately
36 and 42 months for females and males, respectively. Female age at first birth was
about 3 1/2 years. Births were scattered during some years and clustered during others.
The age, rank, and parity of the females affected infant survival. More female than
male infants survived to one year of age. Increased population size was the result
of immigration rather than births.
